我们为什么笑？多年来，科学家们也问自己这个问题。没有其他动物会又大笑又微笑 — 只有人类，如是，笑有助我们生存吗？答案似乎是，微笑和大笑能帮助我们放松，缓和紧张局势，防止由压力造成的疾病。笑确实是最好的良药！
但是，如果你不快乐，微笑也对你也没多用吧，对吗？事实并非如此。明显地，微笑能带来正面影响，不管你想不想笑。在加利福尼亚州的科学家让一组演员演绎五种不同的感受：快乐、悲伤、愤怒、惊讶和恐惧 - 只是他们的脸部表情。
他们的心跳速率改变、血压和体温都记录下来。大部份演绎出来的情绪并没有引起变化，但是当他们微笑时，他们的心跳和血压都下降。即使他们只是演戏也发生这种情况！所以，即使我们心里感到悲伤，微笑似乎让我们感觉好一些。
幽默感也有助于对事物保持积极的看法。如果你能看到事情有趣的一面，即使被朋友打扰或汔车爆胎也不显得太糟糕。所以，如果你发现自己在甚具压力的情况下，尽量让自己傻笑一下。一位心理学家写道：「如果人试图表现出积极以替代消极的反应，这将最终成为他们性格的一部分。如果你开始笑，假以时日，你会真正变得快乐。」

原文如下：
Why do we laugh? For years scientists have asked themselves this question. No other animals laugh and smile--only human beings, so does laughter help us to survive in any way? The answer seems to be that smiling and laughter help us to relax, reducing tension and preventing illnesses which are caused by stress. Laughter really is the best medicine!
But if you're unhappy, it can't do you any good to smile, can it? Not true. Apparently the positive effects of smiling are just the same whether you feel like smiling or not. Scientists in California asked a group of actors to act five different feelings: happiness, sadness, anger, surprise and fear--just using their faces.
Changes in their heart rate, blood pressure and temperature were written down. Most of the feelings they acted didn't cause changes, but when they smiled their heart rate and their blood pressure went down. This happened even though they were only acting! So even if we feel sad inside, smiling seems to make us feel better.
A sense of humor also helps to keep things in perspective. Interfering friends or a flat tyre won't seem quite so bad if you can see the funny side. So if you find yourself in a stressful situation, try to let yourself giggle. A psychologist writes: " If people try to show a positive reaction instead of a negative one, this will eventually become part of their personality. If you start to laugh, in time you will actually become happier."
